3. 系統(tǒng)性能
● 流量脈沖頻率：小于50Hz。對應于各種流量計的流量范圍如表1所列。
● 精度：主要取決于流量計精度，即SPX系列為±1％滿量程；WTX系列為±0.75％滿量程，系列流量脈沖頻率>50Hz時，會產(chǎn)生附加誤差。
● 電源：交流220V。
4. 系統(tǒng)主要功能
本系統(tǒng)可以計算和分路顯示瞬時流量和累積流量，其顯示范圍為：0.0000?2949.0000(l/m)
系統(tǒng)通過顯示器將CPU212中的各路瞬時流量和累積流量顯示出來，并可清零及設置K系數(shù)，其設置方法為：K=3.7854/K′，式中K′為流量計標簽上的K系數(shù)，按四舍五入法則取K的小數(shù)點后4位數(shù)。
5. 結(jié)束語
本系統(tǒng)在工業(yè)生產(chǎn)中有廣泛的應用前景?？梢杂嬎愫惋@示多路瞬時流量和累積流量，精確度高；使用可編程程序控制器使系統(tǒng)的性能價格比較高，同時由于使用了顯示器，系統(tǒng)用戶界面非常友好。分析了水電站PLC系統(tǒng)的工作環(huán)境及對系統(tǒng)運行的影響并提出了相應的措施。
